Factors that Affect Solar Panel Costs in Fairfax
Although the average cost of a solar system in Fairfax is $15,500, your final cost may be above or below the average. There are several factors that can have a major impact on the cost of a solar system installation. Below are some of the more important things to consider.
Solar Equipment
The size of the solar system you need to offset your energy usage, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, your total will most likely increase by nearly $3,850. The type of solar panels and equipment you choose is another factor that will significantly influence costs. Solar panels that are more efficient, like monocrystalline panels, tend to cost more. Moreover, solar equipment is more than just the solar panels themselves. You’ll also need to consider the kind of racks used to mount the panels, inverters, solar batteries, etc. It’s important to take all of this into consideration when researching a solar system that’s in your budget.
Solar Financing Terms
Many homeowners find the average cost of solar in Fairfax to be prohibitively expensive, even if the investment pays off over time. Fortunately, almost every solar company in the area offers financing options. Solar loans drastically decrease upfront costs for most homeowners, but they also lead to higher prices over time due to interest.It’s wise to add the interest you’ll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and how long it’ll take to pay off the loan.
Solar Panel Installation Company
A final consideration when trying to estimate the cost of solar for your home or business in Fairfax is the company you hire to install your PV system. As with choosing a company to build a deck or pool, for instance, there are plenty of solar installers that provide a range of services at different costs.Additionally, some companies in Fairfax are more knowledgeable about local solar incentives and can help you make good use of additional rebates or tax exemptions. However, they may charge more for walking you through the whole process. Even if they cost more upfront, they could help you save more money in the long run.

How to Save on Solar Panels
The solar panel company you opt for will be a major factor in determining not only your overall costs, but also the kinds of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are several important things you should keep in mind, such as:
- Contract: Review the contract terms carefully to make sure you understand how much it will cost, completion timeline rebates and warranties.
- Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for clean energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a good reputation and is qualified to get the job done well. Another way you can look into your installer’s reputation is by reading reviews.
- Installation Process: Get details from your solar installer about the installation process and what to expect, such as when the site survey will be completed and how long it will take.
- Solar Panel Brands: Homeowners will have different preferences for panels depending on their roof configurations and how much efficiency they need. Although there are many options for which kind of solar panel you can get, not every company will have the exact one you may want or need, so make sure you take a look at their list of options before deciding.
